FIG. 1 illustrates the problem setup phase. 100 illustrates selecting an area of the world. For example, an area selected could be Kabul, Afghanistan. 101 illustrates obtaining associated light detection and ranging (LIDAR) data. This can be in the form of airborne LIDAR acquired from aircraft flying overhead or from ground based lidar acquisition. The datasets would be 3-dimensional, such as horizontal and vertical slices per Anderson, K., Hancock, S., Casalegno, S., Griffiths, A., Griffiths, D., Sargent, F., McCallum, J., Cox, D. T. C. and Gaston, K. J., 2018. Visualising the urban green volume: Exploring LiDAR voxels with tangible technologies and virtual models.

At this juncture, the buildings and trees and different mountains would be evident to a ground observer wearing a head display unit, such as the integrated visual augmentation system (IVAS). 103 illustrates selecting a starting coordinate for blue force. A blue force is a term that is used typically for the United States force element. The exercise would typically commence from the starting point and be oriented on the location of a red or opposing force provided by the blue force intelligence. 104 illustrates selecting a starting coordinate for red force. A red force is a term that is used typically for the enemy force element. This need not coincide with the location provided by blue force intelligence. 105 illustrates generating a 3D scene around the blue force. 106 illustrates generating a 3D scene around the red force. 107 illustrates an initial look angle for blue force element #1.

FIG. 2 illustrates movement dynamics for the blue and red forces. This figure illustrates the movement of elements over multiple time sequential time periods. 200 illustrates monitoring blue force movement and updating location. For blue force elements 1-N, has eye location/orientation changed? Had head position/orientation changed? If yes, move to processing block 201. If no, move to processing block 202. At processing block 201, the location of each of the elements would be updated and any changes in the look angles or eye positions would be updated. At this point, a new set of imagery would be created for each of the elements that had changes in these locations or look angles. An example would be that blue force element 3 change his viewing angle from looking North to looking Northeast. After completion of 201, then the move to processing block 202. At processing block, 202, then move to processing block 200. An example would be that blue force element 7 had an unchanged head position/orientation and unchanged eye position/orientation over this time period. For example, blue force element 7 looked North over the entire time period. 203 illustrates monitoring red force movement and updating location. For red force elements 1-M, has eye location/orientation changed? Had head position/orientation changed? If yes, move to processing block 204. If no, move to processing block 205. At processing block 204, the location of each of the elements would be updated and any changes in the look angles or eye positions would be updated. At this point, a new set of imagery would be created for each of the elements that had changes in these locations or look angles. An example would be that red force element 9 change his viewing angle from looking South to looking Southwest. After completion of 204, then the move to processing block 205. At processing block, 205, then move to processing block 203. An example would be that red force element 11 had an unchanged head position/orientation and unchanged eye position/orientation over this time period. For example, red force element 11 looked South over the entire time period.

FIG. 3 illustrates example action dynamics. 300 illustrates wherein the position of the forces is now such that interaction between the forces is possible. 301 illustrates wherein for every element in the blue force, conduct search in the assigned sector. 302 illustrates the decision point of whether blue force element 1-N detected red element(s)? If yes, move to 303. If for example, if blue force element #4 has detected a red element, he/she determines to take actions as follows. 304 illustrates wherein a blue force moves to a position to engage (e.g., behind a rock). 305 illustrates engagement, such as firing a weapon. These actions would typically be coordinated and directed by the blue unit leader. 306 illustrates calling the command element and reporting the actions. If the answer to 302 is no, then move to 307. 307 illustrates continuing to monitor/search. 308 illustrates wherein for every element in the red force, conduct search in the assigned sector. 309 illustrates the decision point of whether red force element 1-M detected blue element(s)? If yes, move to 310. If for example, if red force element #19 has detected a blue element, he/she determines to take actions as follows. 311 illustrates wherein a red force moves to a position to engage (e.g., behind a tree). 312 illustrates engagement, such as firing a weapon. These actions would typically be coordinated and directed by the red unit leader. 313 illustrates calling the command element and reporting the actions. If the answer to 309 is no, then move to 314. 314 illustrates continuing to monitor/search.

FIG. 4 illustrates example after action activities. 400 illustrates at the conclusion of the engagements, the following example activities would take place. Note that during the course of the initial setup to the conclusion of the exercise, there would be continuous recording of all elements' locations, orientations and activities over the duration of the exercise. 401 illustrates for every element of the blue force 1-N, plot movements over time. 402 illustrates indicating points where inter-visibility occurred between blue force and red force. 403 illustrates indicating points where blue engagements took place and results thereof. 404 illustrates rolling up the results data over all blue elements. 405 illustrates for every element of the red force 1-M, plot movements over time. 406 illustrates indicating points where red engagements took place and results thereof. 407 illustrates rolling up the results data over all red elements. 408 illustrates creating a combined report.

No. 9,980,691 can be used to select a region of interest from a large volume. 502 illustrates a weapons performance database (range, accuracy, penetration, etc.). 503 illustrates a sensor performance database (NE ΔT). 504 illustrates an AI soldier assist database. 505 illustrates an exercise database. 506 illustrates other databases, as needed for a particular exercise. 507 illustrates the pseudo-GPS system. 508 illustrates the soldier communication link. 509 illustrates the equipment communication link. 510 illustrates the central processor, which provides terrain updates, a projected scene to soldiers, target acquisition, engagements and results thereof, updates on unit status and records data for after action reviews (AAR). 511 illustrates a transportation mechanism (e.g., virtual treadmill, virtual car, etc.), which are an option for the warehouse concept. 512 illustrates a weapon orientation. 513 illustrates a system status. 514 illustrates a control station. 515 illustrates soldier's pseudo-GPS system. Nominally, the soldier's pseudo-GPS position would be updated as a result of movements (direction and speed and duration) of the transportation mechanism over time. In the event, however, the soldier departed the transportation mechanism, the soldier's position could be computed and the equipment must have an inertial measurement unit (IMU), which could communicate changes in location of the soldier through the GPS system and onto the central processing unit.

Note that having a low ratio of transceivers to users would be cost effective.

FIG. 7 illustrates determining a user's coordinate in the virtual world. 700 illustrates assigning an initial GPS location within the region to the user (e.g., 1 km North of a flag pole in Afghanistan) and viewing angle (e.g., looking South) to the user in an area (e.g., training warehouse at Ft. Benning, Ga.). 701 illustrates wherein the area's transceivers emit a signal. 702 illustrates wherein each user's equipment receive signal and compute location (pseudo-GPS) within the area. Monitor for distance traveled (e.g., walking around the area, walking on treadmill, etc.). Additionally, an updated GPS location within the region is computed. For example, assume a user's initial GPS location is at a building located at 1 km North of a flag pole in Afghanistan. Assume that a user is facing South. The use will initially see in the virtual world in the augmented reality/mixed reality headset, the surroundings at the building. Assume that the treadmill is activated and the user is walking at 2 km/hour on the treadmill oriented Southward in the virtual world, the virtual world displayed on the user's HDU would be slowly changing from the initial building and at approximately 30 minutes, the user would arrive at the virtual flagpole.
